Impressive
Style: Updated Formula
Nice thick cream! I even saw results (skin improvement) within days. I like this way better than their Cicalfate+, as it’s easier to rub in, less greasy, and doesn’t have the water vs cream separation issue. I’m not a huge fan of the pump top for this one, but at least it’s a tube instead of a solid canister (where you can’t see how much is left or get to the last bit).

Not Hydrating Enough

Non greasy but is not moisturizing enough for my dry eczema prone skin.

Excellent for my sensitive skin and rosacea
Another excellent product from this brand. I have type 1 rosacea on my cheeks, even when I avoid triggers (like red wine, warm weather, etc.), and very sensitive skin overall. I've been using the cicalfate serum from this brand for the sensitivity, but it didn't help the redness. After two weeks of using this twice daily, I noticed a significant difference. After a month, I had no redness unless I encountered a trigger. Even then, the intensity of the redness seemed less. I tried going without this product for a month when the first bottle ran out, and sadly, the redness started coming back within a cycle of weeks. I've got this on auto-delivery now, along with the cicalfate serum. I never want to be without it!

Best moisturizer for sensitive skin
I have very sensitive skin and have tried many products over the years. This is by far the best daily moisturizer. I don’t wear makeup other than under eye concealer. This keeps my skin looking and feeling great. Not greasy. One bottle lasts about a month. I have probably bought this 10 times in the past year.

Not as good as the antirougeurs cream
I used to use the Antirougeurs cream and loved it but since they no longer make it, I had to switch. I have been using the redness expert cream for a week and it makes my face even redder. I also started to break out. The texture is good but I don’t think it works like the other cream.
